.SH NAME
ms \- text formatting macros
.SH SYNOPSIS

.SH DESCRIPTION
This package of \fInroff\fP\| and \fItroff\fP\|
macro definitions provides a formatting facility
for various styles of articles, theses, and books.
When producing 2-column output on a terminal or lineprinter,
or when reverse line motions are needed,
filter the output through \fIcol\fP\|(1).
All external \-ms macros are defined below.
Many \fInroff\fP\| and \fItroff\fP\| requests
are unsafe in conjunction with this package.
However, the first four requests below
may be used with impunity after initialization,
and the last two may be used even before initialization:
.sp .2
.ta 5n 12n
.nf
	.bp	begin new page
	.br	break output line
	.sp n	insert n spacing lines
	.ce n	center next n lines
	.ls n	line spacing: n=1 single, n=2 double space
	.na	no alignment of right margin
.fi
.sp .2
Font and point size changes with \ef and \es are also allowed;
for example, ``\efIword\efR'' will italicize \fIword.\fP
Output of the \fItbl, eqn,\fP and \fIrefer\fP\|(1) preprocessors
for equations, tables, and references is acceptable as input.

.SH REGISTERS
Formatting distances can be controlled in \-ms
by means of built-in number registers.
For example, this sets the line length to 6.5 inches:
.sp .3
	.nr  LL  6.5i
.sp .3
Here is a table of number registers and their default values:
.sp .3
.nf
.ta .5i +\w'Name\0'u +\w'paragraph distance 'u +\w'Takes Effect 'u
	Name	Register Controls	Takes Effect	Default
.sp .3
	PS	point size      	paragraph	10
	VS	vertical spacing	paragraph	12
	LL	line length     	paragraph	6i
	LT	title length    	next page	same as LL
	FL	footnote length 	next .FS	5.5i
	PD	paragraph distance	paragraph	1v (if n), .3v (if t)
	DD	display distance	displays	1v (if n), .5v (if t)
	PI	paragraph indent	paragraph	5n
	QI	quote indent    	next .QP	5n
	FI	footnote indent 	next .FS	2n
	PO	page offset     	next page	0 (if n), \(ap1i (if t)
	HM	header margin   	next page	1i
	FM	footer margin   	next page	1i
	FF	footnote format 	next .FS	0 (1, 2, 3 available)
.fi
.sp .3
When resetting these values,
make sure to specify the appropriate units.
Setting the line length to 7, for example,
will result in output with one character per line.
Setting FF to 1 suppresses footnote superscripting;
setting it to 2 also suppresses indentation of the first line;
and setting it to 3 produces an .IP-like footnote paragraph.
.PP
Here is a list of string registers available in \-ms;
they may be used anywhere in the text:
.sp .3
.nf
.ta .5i 1.1i
	Name	String's Function
.sp .3
	\e*Q	quote (" in \fInroff,\fP\| `` in \fItroff\fP )
	\e*U 	unquote (" in \fInroff,\fP\| '' in \fItroff\fP )
	\e*\-	dash (-- in \fInroff,\fP \(em in \fItroff\fP )
	\e*(MO	month (month of the year)
	\e*(DY	day (current date)
	\e**	automatically numbered footnote
	\e*\'	acute accent (before letter)
	\e*\`	grave accent (before letter)
	\e*\d^	\ucircumflex (before letter)
	\e*,	cedilla (before letter)
	\e*:	umlaut (before letter)
	\e*\d~	\utilde (before letter)
.fi
.sp .3
When using the extended accent mark definitions available with .AM,
these strings should come after, rather than before,
the letter to be accented.
.SH BUGS
Floating keeps and regular keeps are diverted to the same space,
so they cannot be mixed together with predictable results.
